DETAILED DESCRIPTION

A photographing lens assembly includes, in order from an object side toan image side, a first lens element, a second lens element, a third lenselement, a fourth lens element, a fifth lens element and a sixth lenselement. The photographing lens assembly has a total of six lenselements with refractive power. Moreover, the photographing lensassembly further includes an image sensor located on an image plane.

The first lens element with positive refractive power has a convexobject-side surface and can have a concave image-side surface.Therefore, the total track length of the photographing lens assembly canbe reduced by properly adjusting the positive refractive power of thefirst lens element.

The second lens element can have negative refractive power and a concaveimage-side surface, so that it is favorable for correcting theaberration generated by the first lens element.

The fourth lens element with positive refractive power can have aconcave object-side surface and a convex image-side surface. Therefore,it is favorable for balancing the arrangement of the positive refractivepower so as to avoid overloading the positive refractive power on onesingle lens element resulting in excessive spherical aberrations. It isalso favorable for correcting the astigmatism.

The fifth lens element with negative refractive power has a convexobject-side surface and a concave image-side surface. Therefore, thePetzval sum of the photographing lens assembly can be correctedeffectively, so that the peripheral field of view can be better focusedon the image plane in order to improve resolving power. Moreover, theobject-side surface of the fifth lens element changes from convex at aparaxial region thereof to concave at a peripheral region thereof, andthe image-side surface of the fifth lens element changes from concave ata paraxial region thereof to convex at a peripheral region thereof. Thefifth lens element has at least one inflection point on at least one ofthe object-side surface and the image-side surface. Therefore, theaberration of the off-axis can be further corrected.

The sixth lens element with negative refractive power can have a convexobject-side surface and has a concave image-side surface. Therefore,with the negative refractive power of the fifth lens element, theprincipal point of the photographing lens assembly can be positionedaway from the image plane, and the back focal length thereby can beshortened so as to reduce the total track length. Furthermore, theobject-side surface of the sixth lens element is convex at a paraxialregion thereof and comprises two inflection points between the paraxialregion thereof and a peripheral region thereof, and the sixth lenselement has at least one inflection point on at least one of theobject-side surface and the image-side surface. Therefore, the angle atwhich the incident light projects onto the image sensor from theoff-axis can be effectively reduced, and the aberration of the off-axiscan be further corrected.

A projection point of a maximum effective diameter position on theimage-side surface of the sixth lens element onto an optical axis iscloser to an imaged object than an axial vertex on the object-sidesurface of the sixth lens element. Therefore, the change of the surfaceshape of the image-side surface will be more obvious which is favorablefor effectively correcting the peripheral aberration.

When a focal length of the fifth lens element is f5, and a focal lengthof the sixth lens element is f6, the following relationship issatisfied: 0<f6/f5<1.2. Therefore, it is favorable for effectivelycorrecting the peripheral aberration of the photographing lens assemblyand not resulting in a curved image plane. Preferably, the followingrelationship is satisfied: 0.2<f6/f5<1.0.

When an axial distance between the object-side surface of the first lenselement and the image-side surface of the sixth lens element is TD, amaximum image height of the photographing lens assembly is Y, and anaxial distance between the image-side surface of the sixth lens elementand the image plane is BL, the following relationship is satisfied:(TD/Y)+(BL/Y)<1.65. Therefore, it is favorable for reducing the backfocal length of the photographing lens assembly so as to reduce thetotal track length for maintaining a compact size.

When an axial distance between the second lens element and the thirdlens element is T23, and an axial distance between the third lenselement and the fourth lens element is T34, the following relationshipis satisfied: 0.5<T34/T23<1.7. Therefore, it is favorable for assemblingthe lens elements so as to increase the manufacturing yield rate.

When a focal length of the photographing lens assembly is f, and thefocal length of the sixth lens element is f6, the following relationshipis satisfied: −1.5<f/f6<−0.64. Therefore, the principal point of thephotographing lens assembly can be positioned away from the image plane,and the back focal length together with the total track length therebycan be reduced through properly adjusting the focal length of the sixthlens element.

When an Abbe number of the second lens element is V2, an Abbe number ofthe third lens element is V3, and an Abbe number of the fifth lenselement is V5, the following relationship is satisfied:15<(V2+V3+V5)/3<40. Therefore, it is favorable for correcting thechromatic aberration. Preferably, the following relationship issatisfied: 15<(V2+V3+V5)/3<30.

When a curvature radius of the object-side surface of the fifth lenselement is R9, and a curvature radius of the image-side surface of thefifth lens element is R10, the following relationship is satisfied:0<(R9−R10)/(R9+R10)<0.4. Therefore, the astigmatism of the photographinglens assembly can be effectively corrected so as to improve theresolving power.

When a distance in parallel with the optical axis from the maximumeffective diameter position on the object-side surface of the fifth lenselement to an axial vertex on the object-side surface of the fifth lenselement is SAG51, and a central thickness of the fifth lens element isCT5, the following relationship is satisfied: −3<SAG51/CT5<−0.5.Therefore, the surface shape of the lens elements will not beexcessively curved which is thereby favorable for manufacturing andassembling the lens elements so as to keep the photographing lensassembly more compact.

When an incident angle of the chief ray at the maximum image height onthe image plane is CRA, the following relationship is satisfied: 30degrees<CRA<50 degrees. Therefore, it is favorable for controlling theangle at which the incident light projects onto the image sensor so asto improve the responding rate of the image sensor for achieving betterimage quality.

When an f-number of the photographing lens assembly is Fno, thefollowing relationship is satisfied: 1.2<Fno<2.3. Therefore, it isfavorable for making the photographing lens assembly obtain largeaperture so as to take sharp images under insufficient light conditionsby fast shutter speed.

When an axial distance between the fourth lens element and the fifthlens element is T45, and an axial distance between the fifth lenselement and the sixth lens element is T56, the following relationship issatisfied: 0<T45/T56<0.27. Therefore, it is favorable for assembling thelens elements and effectively reducing the total track length of thephotographing lens assembly so as to keep a compact size.

When a focal length of the fourth lens element is f4, and the focallength of the sixth lens element is f6, the following relationship issatisfied: −3.0<f4/f6<−0.68. Therefore, it is favorable for reducing thephotosensitivity and the total track length of the photographing lensassembly.

According to the photographing lens assembly of the present disclosure,the lens elements thereof can be made of glass or plastic material. Whenthe lens elements are made of plastic material, the manufacturing costscan be effectively reduced. When the lens elements are made of glassmaterial, the distribution of the refractive power of the photographinglens assembly may be more flexible to design. Furthermore, surfaces ofeach lens element can be aspheric, so that it is easier to make thesurfaces into non-spherical shapes. As a result, more controllablevariables are obtained, and the aberration is reduced, as well as thenumber of required lens elements can be reduced while constructing thephotographing lens assembly. Therefore, the total track length of thephotographing lens assembly can also be reduced.

According to the photographing lens assembly of the present disclosure,when the lens element has a convex surface, it indicates that thesurface is convex at the paraxial region; and when the lens element hasa concave surface, it indicates that the surface is concave at theparaxial region.

According to the photographing lens assembly of the present disclosure,the photographing lens assembly can include at least one stop, such asan aperture stop, a glare stop, or a field stop, etc. Said glare stop orsaid field stop is allocated for reducing stray light while retaininghigh image quality.

Furthermore, an aperture stop can be configured as a front stop or amiddle stop. A front stop which can be disposed between an object andthe first lens element provides a longer distance from an exit pupil ofthe system to an image plane and thereby the generated telecentriceffect improves the image-sensing efficiency of the image sensor. Amiddle stop which can be disposed between the first lens element and theimage plane is favorable for enlarging the field of view of the systemand thereby provides a wider field of view for the same.

According to the photographing lens assembly of the present disclosure,the photographing lens assembly is featured with good correction abilityand high image quality, and can be applied to 3D (three-dimensional)image capturing applications, in products such as digital cameras,mobile devices and tablets.
